    Nutritive evaluation of prawn waste for growth in large white yorkshire pigs

    An experiment was conducted to assess the nutritive value of prawn waste for growth in Large White Yorkshire pigs. Thirty female pigs with an average body weight of 31.4 kg were divided into three equal groups as uniformly as possible with regard to age and body weight. The three groups of pigs were maintained on three different experimental diets viz., Tl control standard grower (16 per cent CP) and finisher ration (14 per cent CP), T2 - 25 per cent of total protein in Tl replaced by protein from prawn waste and T 3 - 50 per cent of total protein in T 1 replaced by protein from prawn waste. The average daily gain recorded for the three groups T1, T2 and T3 were 385.5, 393.3 and 381.1 g respectively. The cumulative feed conversion efficiencies were 4.87, 4.73 and 4.89 for the groups T1, T2 and T3 respectively. The digestibility coefficients of nutrients were significantly higher in T2 for dry matter (p<0.05) and crude protein (pwas found significantly higher (p and T2. The digestibility coefficients of crude fibre and ether extract were almost similar for all the three groups. Study of the carcass characteristics revealed that dressing percentage, carcass length, back fat thickness, loin eye area and ham weight were not significantly influenced by the inclusion of prawn waste at different levels. The cost of feed per kg weight gain of animals in different treatments Tl and T2 and T3 were Rs. 29.95, 23.84 and 21.18 respectively. The above results indicate that, prawn waste can be used economically to replace the protein of the grower and finisher rations for pigs up to 50 per cent level.
